# Iroko Framework: Ewé Module (Turtle)
# File: docs/vocab/iroko-ewe-module.ttl
# Canonical module URI: https://iroko-framework.github.io/iroko-ewe-module/
# Serialization URI:     https://iroko-framework.github.io/iroko-ewe-module/vocab/iroko-ewe-module.ttl
#
# Scope
# - SKOS concept schemes for controlled description (access, medicinal use, ritual use)
# - A minimal domain class (iroko:Plant) included for future RDF modeling without forcing it now
#
# Design notes
# - Option A enforced: term URIs follow filename slugs (including "and" where present)
# - Concept URIs are clean (no ".md"); web pages may still be ".md" while URIs remain stable identifiers
# - Schemes are dereferenceable folder URIs ending with "/"
